Multiple choice

A nematode Meloidegyne incognitia infects the roots of tobacco plants and causes a great reduction in yield. It can be prevented by RNA interference (RNAi). What does this method involve?

  1. Silencing of a specific DNA due to a complementary dsRNA molecule that binds to and prevents translation of the mRNA.

  2. Silencing of a specific tRNA due to a complementary dsRNA molecule that binds to and prevents translation of the mRNA.

  3. Silencing of a specific mRNA due to a complementary ssRNA molecule that binds to and prevents translation of the mRNA.

  4. Silencing of a specific mRNA due to a complementary dsRNA molecule that binds to and prevents translation of the mRNA.

  5. Silencing of a specific rRNA due to a complementary dsRNA molecule that binds to and prevents translation of the mRNA.
